Predicting qualitatively how entropy changes with mixing and separation For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour.

This question has multiple parts. Work all the parts to get the most points. Use the References to access important values if needed for this question. The Gibbs Free Energy equation is given by the equation: AG=AG + RTln Q - Where: AG = Gibbs Free Energy change AG = Standard Gibbs Free Energy change T= temperature In Q = natural log of the reaction quotient In order to solve for the temperature, T, in two steps you must: Step One Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the expression: (Be sure that the answer field changes from light yellow to dark yellow before releasing your answer.) +AG = +AG + RT In Q Drag and drop your selection from the following list to complete the answer: 1 -AG AG AGⓇ AGⓇ Submit
Consider the combustion of one mole of methane gas:CH4(gas) + 2O2(gas) --> CO2 (gas) + 2H2O(gas).The system is at standard temperature (298 K) and pressure (105 Pa) both before and after the reaction. 1.) First imagine the process of converting a mole of methane into its elemental consituents (graphite and hydrogen gas). Use the data at the back of this book to find ΔH for this process. 2.) Now imagine forming a mole of CO2 and two moles of water vapor from their elemental constituents. Determine ΔH for this process. Question: How much heat is given off during this reaction, assuming that no "other" forms of work are done?
